"Hospi" is a hospitality robot being tested at the ANA Crowne Plaza Narita.

It moves around the lobby with a smile on its screen, informing guests about bus schedules and handing out water bottles. Next week, "Hospi" will be moved to work on collecting dirty dishes at Tokyo's main airport.

The robot is already being used to deliver medicines and supplies in hospitals. But its designers want to demonstrate that it can also work in customer service setttings.
